    Patent number: 4418277
    Abstract: An apparatus for use with merchandise bearing an optically readable code, including a portable wand reader which transmits a coded infrared signal to a stationary receiving/transmitting unit coupled to a data processor, which in turn emits a signal for transmission back to the wand so that it can be checked against the original signal in order to detect communication errors. A number of physically separated receiving/transmitting units may be coupled to the data processor in order to permit the wand to be used within a large region or in order to permit a number of wands to be used simultaneously.A keyboard may be coupled to the wand for use with non-coded data, as when the price marked on the merchandise is verified.
